Let’s talk about each of the features it offers in details.

Stellar Phoenix Mailbox Exchange Recovery

Microsoft Exchange Database uses Extensible Storage Engine (ESE) for the database architecture. Exchange database contains different mailboxes like users, shared, room, etc. Each mailbox has various items types like messages, attachments, calendar, notes, contacts, tasks and is hierarchically stored in the different folders. There are many reasons to for the mailbox database corruption; it could be because of hardware or logical corruption. These corruptions are irreversible.

Stellar Phoenix Mailbox Exchange Recovery feature is to recover the corrupted Exchange database (EDB) file and export the data in the usable format. Exchange database correction rarely occurs and but when it occurs, then we are in deep trouble. Organizations offer large mailboxes for the users, and details size growth is enormous. Recovering the large database using the native Exchange ESEUTIL /P command takes forever. If ESEUTL /P sometimes may not fix the issue and end up to start over from the beginning. Phoenix Mailbox Exchange Recovery helps to overcome all the Hazel of running ESEUTIL repair and all the wait time. It can connect to the database, fixes the Database corruption and then export the mailboxes content to the target mailbox. Alternatively, we can even export the mailboxes content to PST, MSG and EML files.

Steps to Recovery Exchange Mailbox Database

1. Start Stellar Phoenix Mailbox Exchange Recovery

2. Connect to the offline EDB file using Select EDB option or use Find EDB to find the EDB file on the local machine

3. It has two scan options Quick Scan and Extensive Scan. A quick scan can fix most corruption, but extensive can give better results.

4. Once it repairs the EDB file, it lists all the mailboxes available in the EDB database file.

5. We can select the individual mailbox and export the content in the required format list PST. MSG, EML formats. It can even export the connect to the user’s Exchange mailbox or office 365 mailboxes.

6. We can also export the individual mailbox item or even the contents of the mailbox folder to the required format.

Stellar Mailbox Extractor for Exchange Server

Microsoft Exchange Database uses Extensible Storage Engine (ESE) for the database architecture. Exchange database contains different mailboxes like users, shared, room. Each of the mailboxes has various items types like messages, attachments, calendar, notes, contacts, tasks and is hierarchically stored in the different folders. These items can get corrupted for various reason, and natively there are limited options to fix it. Many exchange administrators move the mailbox from database to another database. During the mailbox move, it copies the items which are not corrupted and leaving the corrupted items. However, this solution does not fix the corrupted messages and get it in the readable format.

Stellar Mailbox Extractor for Exchange Server feature can connect to the online or offline Exchange database and select the required mailbox and export to PST. It also allows preview each of the items in the mailbox and export one or more articles in the required format like HTML, RTF, PDF and others supported formats.

Stellar OST to PST Converter

Stellar OST to PST Converter is to convert OST files to your local machines to the PST file format, and it can split the PST into multiple management PST files. It can even export the email content to the Exchange Server mailbox or even to office 365 mailboxes.

This feature comes in handy when you have the corruption in a mailbox or database or even the loss of Exchange server itself. OST to PST help you to overcome the situation, and it scan the OST file on the local user’s machine and can restore the content to the PST. Outlook 2007 and above supports Unicode version PST, and they can be as bigger as 50 GB and more. OST to PST Converter can also export the content to Exchange mailbox or Office 365 mailbox. It also allows to saves the individual or email box content in different format like MSG, EML, HTML, RTF, and PDF

Stellar Mailbox Extractor for Exchange Backup 8.0

Stellar Mailbox Extractor for Exchange Backup is to features to restore the mailboxes or mailbox contents from Exchange Backup. Exchange Backups are a necessary component of Exchange infrastructure. Most of the Organizations do a backup on daily basis, and there are often requirements to restore the content from backups. Many a times Mailbox content restore a full-time activity, and it involves a lot of efforts and time using native Exchange.

Stellar Mailbox Extractor for Exchange Backup can connect to the Exchange Backup files and quickly scan through the content and lists all the mailboxes available in the backup files for restore. The administrator can select the one or more user mailbox and save the content to PST. It also allows the administrator to save mailboxes or individual email content to file formats like MSG, EML, HTML, RTF, PDF, and even to office 365. This software also helps to repairs Windows NT Backup file and Symantec VERITAS Backup Exec file with BKF formats.

Stellar Phoenix Password Recovery for MS Exchange

Stellar Phoenix Password Recovery for MS Exchange is not an Exchange component, but it is for Microsoft Windows Server. It helps to break the windows server local administrator password. There are many situations where we need to log in as a local administrator, but administrator does not have the local password. It supports Microsoft Windows 2000 Server, 2003 Server, 2008 Server and 2012

Stellar Phoenix Password Recovery for MS Exchange required to download Boot image ISO from the website and burn it to a CD. Make necessary changes in the BIOS to boot from the CD and boot the server using it. Finally, use ResetPassword.exe to restart the password of the administrator and reboot the machine.

Conclusion:

To perform some of the operations on the Exchange online mailbox database, we need to have the necessary permission to connect, and preferably we need full mailbox access. I think Stellar Exchange Toolkit is a great tool and necessary required for Exchange Server Administrators. I can honestly say I loved this product. This application not only worth its cost but also have amazing features such as user-friendly interface, scanning speed, flexible recovery & export option & live preview option. I would definitely give a 5/5 rating where the software met and exceed my expectations.

Cloud-based migration is a next generation migration option that readily reduces the chances of corruption and makes accessibility of files quite easy. As far as OST files are concerned, they are also preferred to be migrated in the same platform without any worries. Doing so makes them all time available back-up of required files. Moreover, the cloud can be accessed from anywhere at any time and can be even used for bulk migration.

Thus, the required OST files become safe and handy on few clicks. However, few questions protrude while we think of OST files. It relates to “What happens if OST files get corrupt?” “Will it anyhow affect the existence of PST?” If how, then what will be the concerning factors?

To make the picture clearer it must be clear that the initial focus is to rescue the damaged OST files content and try to keep data hierarchy unchanged without any issues. To be answerable in such unexpected circumstances it is necessary to avail some technical assistance from reliable third-party tool.

Managing spoilt OST files

There is high probability of getting OST files affected by corruption. However, the severity of OST file corruption is beyond the scope of the topic, but its impetus may somehow put a massive effect on entire file structure.

Managing spoilt OST files

There is high probability of getting OST files affected by corruption. However, the severity of OST file corruption is beyond the scope of the topic, but its impetus may somehow put a massive effect on entire file structure.

Figure 1 Dialog Box presenting technical issue.

You must be introduced to the dialog box that displays the inaccessibility information. It is not the single note; moreover, there are ample of them that convey the same message in other manner.

However, assistance from third-party proved to be helpful. Kernel for OST to PST is the most convenient and user-enabled third-party tool, which is often recommended for this purpose. This OST to PST tool simply scans for damaged/corrupt OST files and repairs them keeping OST file hierarchy and data structure unchanged. Moreover, the tool provides an option either to directly migrate the OST files to cloud-based platforms or convert same to PST and other file formats like DBX, MBOX, MSG, EML, TXT, RTF, HTML, MHTML, & PDF.

What takes for restructuring lost OST files?

Kernel for OST to PST makes use of inbuilt QFSCI algorithm to regain the lost file structure of OST files, it also includes resurrection of OST files content. So, to restructure the damaged OST files Kernel for OST to PST makes use of few essential steps, which include selection of concerned OST files, their preview post conversion and their migration/conversion as per user’s choice. The entire process is done within few clicks and conversion/migration entirely depends upon user’s choice.

Cloud-based Migration-User’s choice

Being a choice of next generation, cloud-based migration is being effectively used and recommended by many users. Kernel for OST to PST provides such option in addition to the conventional methods of saving OST files in other formats. The screenshot of the tool clearly shows the effectiveness of the tool in handling the OST data in conventional process and cloud-based migration that involves email servers, webmails and Office 365.

Figure 2 Screenshot of Kernel for OST to PST presenting different options.

About Kernel for OST to PST

Kernel Data Recovery has designed a more secure way than conventional methods that were quite risky and time consuming. A more dedicated tool – Kernel for OST to PST has been crafted for this purpose. Kernel for OST to PST uses a secure way to convert OST files to other file format. Thus, it brings a clear picture to the user that OST files can be saved in other formats as well with same dedication and precision as it does for PST file format. Even if the obtained files are large in size, then it can be split in required size. For lost OST files Kernel for OST to PST provides ‘Search’ option. The ‘Preview’ option lets user to make sure that entire conversion has been perfectly taken place. This option provides preview of converted items.

With the below mentioned descriptive figure you can understand the exact functioning of the tool.

For secure OST migration to cloud-based platforms it is recommended to take assistance from reliable third-party tool like Kernel for OST to PST. Due to provision of secure migration and conversion, this tool is highly advised. Since cloud-based migration provides effective and convenient access to OST files; therefore, it is regarded as future cloud for MS Outlook users.

When users are been migrated from On-Prem to Office 365 using some third party tool then the on-prem user object’s Exchange GUID gets rested to “00000000-0000-0000-0000-000000000000" . This will cause problem when we need to move back the mailbox to on-prem for some reason. Below is the code which helps to validate the On-prem users which Exchange GUID and copy back the Exchange GUID properties from Online mailbox to the Exchange On-prem user.

In Part 1 and Part 2 of the article series, we deployed Exchange 2013 servers in each AD site, deployed Kemp LoadMaster and configure it for Exchange services in each AD site.

In this final part of the article series, we will configure LoadMaster with Global Balancing, where if Dallas AD site goes down then client request (internal and external) will route to Exchange 2013 servers in the Pittsburg AD site and vice versa. Global Balancing provide redundancy for both Exchange and LoadMaster itself. Below is the figure 3.1 is the current diagram for the Exchange 2013 lab using Kemp Free LoadMaster

Figure 3.1 Exchange 2013 and Kemp LoadMaster LAB configuration.

Configure Static Routes on Kemp LoadMaster

From the above Figure 3.1, Dallas LoadMaster Eth0 interface is configured with network 192.168.1.0/24 network and LAB router with DHCP have assigned DNS and Default gateway for this interface. Using DNS and default gateway, Eth0 interface can reach any external network including Pittsburg Eth0 interface.

Figure 3.2 DNS Name Server IP address

But, Dallas LoadMaster Eth1 interface is on 10.10.10.0/24 and it does not configured with DNS and default gateway. Since, two network interface (NIC) on the same machine cannot be configured with two different DNS and Gateway. Hence Eth1 interface has no information on how to reach Eth1 network (20.20.20.0/24) of Pittsburg LoadMaster or any other network internally. To archive this, we need to add manual static routes on the Dallas LoadMaster. Below is the steps to configure the same.

Similarly, Pittsburg LoadMaster Eth1 interface is on 20.20.20.0/24 and it is not configured with DNS and default gateway. It has no information on how to reach Eth1 10.10.10.0/24 Dallas network or any other network. Hence we need to add static routes on the Pittsburg LoadMaster to reach Dallas Eth1. Below is the steps to configure the same.

1. Connect to Pittsburg Loadmaster using Internet Explorer

2. From the Left menu , expand System Configuration -> Additional Routes

3. Add route to reach 10.10.10.0/24 network using gateway 20.20.20.101 (It is the default gateway for 10.10.10.0/24 network). Below is the reference image.

Figure 3.4 Adding new Fixed Static Routes on Pittsburg LoadMaster

Configuring LoadMaster to Synchronize Configuration each other:

Synchronization lets to replicate the configuration changes or additions done one LoadMaster to another. Below are the steps to synchronize two LoadMaster on Dallas and Pittsburg network.

6. To provide better health check for the HTTPS services, change the checker from ICPM Ping to TCP Connect for the Virtual IP Address on port 443 and then click on Set Addr

Figure 3.11 Configure Mail.happy.com FQDN with Health settings to determine the availability of the services.

7. We could now see that all the Servers are Available and healthy and ready to take connection for mail.happy.com

Configuring Global Balancing for FQDN – autodiscover.happy.com

Since, we have one Virtual IP for all the Exchange HTTPS services on each LoadMaster, we would need to create another FQDN name autodiscover.happy.com and follow the same instruction provided for same IP address and port number used for FQDN name mail.happy.com.

4. Input each of the internal and external Virtual IP (VIP) address of both Dallas and Pittsburg LoadMaster and click Add Address. Then, make sure that checker is to set TCP connect for port 25.

Figure 3.14 Adding External VIPs for smtp.happy.com FQDN

Since Dallas and Pittsburg is configured to sync with each other, we should be able see the configuration synced from Dallas LoadMaster to Pittsburg LoadMaster in real-time. To validate the same, connect to Pittsburg LoadMaster and Navigate to Global Balancing -> Manage FQDNs.

We are almost done with the LoadMaster configuration at both Dallas and Pittsburg AD site. Now we need to configure Internal and External DNS with delegated subdomain for mail.happy.com and autodiscover.happy.com pointing to LoadMaster Virtual IP Address defined in the below table.

To accept SMTP emails from internet for happy.com, configure MX records on the external DNS to point to the external DNS VIP of both Dallas and Pittsburg LoadMaster and below are the details.

This configuration will help clients to connect to all the HTTPS service and also mail flow between internal and internet.

Below is the final diagram with complete IP Address, DNS, LoadMaster and Exchange server details.

Figure 3.15: Final LAB diagram

Finally, we are at the end of the articles series, completely installed, configured Kemp Free LoadMaster in both the AD sites and also configured Global balancing between the sites. Same steps can be followed to implement LoadMaster in production environment, but we need public IP address NATed to the DMZ VIPs to communicate with other external domains.

In part 1 of the article series, we got Exchange 2013 configured, Hyper-V networks configured and installed LoadMaster in both the AD site and finally configure with Two-Arm networks. In this part of the article series we will configure LoadMaster for Exchange HTTPS and SMTP services. Below Figure 2.1 is the current lab setup with IP address configuration.

Figure 2.1 Current lab setup with IP address configuration.

Importing Exchange Kemp Templates into the LoadMaster

Kemp offers free templates for Exchange 2013 with preconfigured settings. These preconfigured templates are based on the Microsoft best practice and helps us to keep our configuration simpler and quicker. These configurations can further tweaked to suites the complex environment and business requirements.

In this part, we will configure one Virtual IP for all the Exchange 2013 HTTPS virtual services. HTTPS virtual services include OWA, EAC, Active sync, Outlook anywhere and EWS. We can also configure one virtual IP for each Exchange services. It is complex to configure but provides better redundancy for each of the Exchange services.

Follow the below steps to configure Dallas LoadMaster with one Virtual IP address for all the Exchange HTTPS services.

SMTP Virtual services help to route email between internal and external network. Internet MX records must be configured to these external Virtual Address so internet emails are delivered to it. LoadMaster process the Internet email and forwards to the internal Exchange servers. Similarly Internet email from internal are accepted by the LoadMaster and it will be process delivered to external. Below are the steps to configure the same:

We have almost done with the configuration of LoadMaster in the lab and below Figure 2.18 is the final Exchange 2013 LAB using Kemp Free LoadMaster. It has all the necessary VIP address for client connection.

Figure 2.18 Exchange 2013 LAB using Kemp Free LoadMaster

Importing Exchange 2013 Certificate into the LoadMaster

Currently LoadMaster is not configured with SSL Offloading. SSL Offloading terminates the client SSL connection at the LoadMaster and generate the new connection to the Exchange server in the backend. This improve the security and performance for client connection. This is an optional settings and below are the steps to perform the same:

1. Export the SAN Certificate from the Exchange server 2013 with private key in PFX format and password.

6. Enable SSL Acceleration and Reencrypt option. Then set the available Exchange certificate and move it to assigned certificates. Lastly select Best Practices under Cipher set and click on Modify Cipher Set.

Follow the above instruction from step 1-6 on the Pittsburg LoadMaster to import the Exchange certificates and configure SSL offloading.

We are almost at the end of the Part 2 article series and configured with LoadMaster for Exchange 2013 HTTPS and SMTP Services. In the next and final part of the article series, we will configure Geo Redundancy. Which allows clients to connect to the available Exchange servers, if any of the Exchange servers/services /AD sites goes down.

In this article series, we will understand the step by step instruction to deploy Kemp LoadMaster for Exchange Server 2013 services in multi- site (Dallas and Pittsburg) lab environment and also configure geo-redundancy between the two AD sites. Where the Kemp LoadMaster load balances the client requests( from internal and internet network) within the AD site and also routes the client request automatically to the available Exchange 2013 servers in other site when one AD site goes down.

Current LAB Setup

Current Lab is built on Microsoft Hyper-V and it is configured with two AD sites Dallas (10.10.10.0/24 network) and Pittsburg (20.20.20.0/24 network). It is also installed with domain controller on each site with the domain name happy.com. In each of the AD site, one Exchange Server 2013 (multirole) is installed and configured Database Availability Group (DAG01) between them. Below Figure 1.1 has the details of the AD sites, Domain Controller, Exchange nodes and DAG.

Figure 1.1 Exchange 2013 deployed in the lab environment.

LAB Hyper-V Virtual Network Configuration Requirement:

LoadMaster interfaces with both internal network and external/internet network. Hence, Hyper-V needs to configure with two Virtual networks: DMZ Network and Internal Network.

1. DMZ Network: Create a new DMZ Network virtual network of type External network, it should connect to the host Machine network interface card (NIC) and communicates with the external world. Make sure to select Allow management operation system to share this network adapter. The Figure 1.2 has the details of the same. Host machine NIC should be connected to the internet.

A Windows VM is configured as Router with two NICs pointing to internal network. This windows Router will route traffic between two network segment Dallas (10.10.10.x) and Pittsburg (20.20.20.x) within the internal network.

Configuring Kemp LoadMaster in the Exchange 2013 lab

In this part , we will Install and configure LoadMaster on both the AD site in Two-Arm Deployment as defined in the below Figure 1.4. With one NIC pointing the DMZ network and other NIC pointing to the internal network.

3. Start Hyper-V Manager and click on Import VM from the Actions menu then click on Next at the Welcome Screen.

Figure 1.6 Importing LoadMaster Virtual Machine into Hyper-V

4. At Local Folder page, Click on Browse button to specify the Kemp LoadMaster virtual machine and click Next and on Select Virtual Machine page keep the settings as default and click on Next

8. Once activated, it will prompt to reset the default user (bal) password. Once password is changed then re-login back to the VM using new password.

Configuring LoadMaster Network Interface

1. Login to Kemp LoadMaster from Internet Explorer and under Main menu expand system configuration -> interface

2. Select eth0 (Network Interface 0) and validate IP Address – 192.168.1.100/24. It is been assigned by DHCP and we could use the same on the interface and change it if required. Make sure Use for GEO Responses and Request is checked and this interface will be used to communicate with Pittsburg LoadMaster for geo redundancy.

Figure 1.17 Configuring LoadMaster eth0 Interface

3. Select eth1 (network Interface 1) and assign the IP address 10.10.10.9/24 from the Dallas internal network segment and click on Set Address. This interface will be used to communicate with internal Exchange 2013 servers in the Dallas and Pittsburg AD sites.

With this we are at the end of the part 1 of the article service with Exchange server 2013 installed and configured, Hyper-V networks configured and finally installed and configured LoadMaster in both the AD site. In the next part we will configure the LoadMaster for the Exchange HTTPS/ SMTP Services and validate the same.

Microsoft Exchange Server 2016 is new latest version of Exchange server and it is been enhanced from Exchange 2013 and it is built on proven Office 365 model. It provides the same look and feel of Exchange 2013 but it offers more stability,reliability, better fault tolerance and self-healing capabilities.

Exchange 2016 can co-exists only with Exchange 2010 SP3 RU11 and above, Exchange 2013 CU10 and above. But it cannot co-exist with Exchange 2007 or any previous versions of Exchange.

Exchange 2016 inherits most of the features from Exchange 2013 and below are some of the new features in addition to the existing feature of Exchange 2013

Architecture enhancements

Microsoft simplified the architecture by consolidating the Client access role and Mailbox role of Exchange 2013 into one mailbox server role and Edge transport server role. This integration of roles reduces hardware, implementation, and management efforts and in some usage scenarios lower licensing costs.

Client features

· Outlook Web Access (OWA) is now called as ‘Outlook on the Web’. It can work together with SharePoint 2016 or OneDrive for Business to share and edit documents. Recipients are automatically provided permission to edit the document. This allows recipients to manage and edit a document without going to SharePoint.

· Search has been significantly enhanced in Exchange 2016. Outlook 2016 and Outlook on the Web provide the same search results. Search speed has also been significantly increased and calendar items can now be searched from Outlook on the Web.

· Outlook 2016 introduces a new Clutter folder that store low priority messages. Outlook itself can assign a low priority to emails based on the past user actions on the emails.

· The Smarter Inbox features helps to increases emails and document search efficiency and productivity.

· The “Tell me what you want to do” box helps users to easily find specific outlook functions or search the web.

· Some great enhancement in Outlook on the Web are one click archiving, common typos/suggestion, the ability to import contacts from CSV files, better formatting features, better attachment views, inline replies, inline previews of URLs and videos and many more.

Mobile enhancements

· Mobile users are new getting rich user experience on phones and tablets. Search on mobile devices has been improved to provide better search results. Two new tabs in the mobile clients: Focused and Others. Where the ‘Focused’ tab will contains all the important email and the ‘Other’ tab is supposed to contain relatively unimportant emails such as newsletters, notifications, subscriptions, etc.

· The mobile calendar view has been greatly improved and it provides more detailed information of invites and other necessary information.

Security and compliance features

· Data Loss Prevention (DLP) has been enhanced and now it can identify, monitor, and protect 80 different types of sensitive information.

· Auditing has been enhanced and updated with a new architecture. Audit logs are no longer stored in individual mailboxes but they are now stored in the centralized audit report mailbox of the organization. This is helpful for long term retention and adds the ability generate various reports easily.

· eDiscovery search has been improved significantly to provide more accurate , faster and reliable results.

· eDiscovery Compliance Search can be used to search on very large numbers of mailboxes. Multile searches can be performed at the same time.

· Public folder content can be on placed on In-place hold and public folder contents can be searched using the eDiscovery.

Exchange 2016 has discontinued Client Access Server and RPC over HTTP protocol for client connection from Exchange 2013. Exchange Server 2016 is great new release of Microsoft’s mail server. It simplifies administration, improves the integration with Office 365 and together with Outlook 2016 and OWA 2016 it helps improve productivity of end users.
